To all whom it may concern:

Be it known that, I. Locus Wnrc'rra. a subject of the King of Great Britain. and a resident of New Rochelle. count-y of Westchester. in the State of New York. have invented certain new and useful Improvements in Coke-Oven Doors. of which the following reference being had'to the accompanying drawings, which form a part thereof.

My present invention relates to coke oven doors. and articularly to doors for coke liorizontal coking chamber type, and has for its general object the provision of an improved form of removable closure for the ends of the coking chambers. A more specific object of my invention is to provide a. novel coke oven door construction for use n a coke oven having the face of the ovengrooved ahove the ends of the cokinn chambers so that the door closinethe end of a coking chamber may extend into the coking chamber like an ordinary plug" door. hut may he opened by moving it ver til-ally upward from its closing position through the correspondinggroove without. first moving the door horizontally out of the doorway as is commonly necessary in coke ovens having plug doors as heretofore constructed. a

Tho various features of novelty which characterize my invention are pointed out with particularity in the claims annexed to and forming a parrot this specification. For a better understanding of the invention, howmer. and the advantages possessed by it. reference should behad to the accompanying drawings and ldescriptive matter in which I have illustrated and described a preferred embodiment of my invention. Of the drawings: 7 -Figure 1 is a partial side elevation of a coke oven structum.

Fig. 2 is a partial section on the line 2-'2 of Fig. 1.

Fig- 3 a plan view of a portion of the coke oven structure shown in Figs. 1 and 2, with the left hand portion of the figure in section on the line 33 of Fig. l, and

Fig. 4 is a partial sectional elevation taken similarly to Fig. '2. showing an upper portion of the oven structure.

In the drawings A represents the masonry oven structure. proper. of a typical modern by-product coke oven formed with horiof these grooves B. WlllCIl are sepazontal coking chambers with heating rated by heating walls formed fines or combustion chambers t. .\.-1 shown. the oven structure is formed with vertical 2TOO"ES A in the oven side wall. at which one end of each. coking chamber B opens. Each groove A extends from the top of the corresponding coking chamber B to the top surface of the oven structure. proper. Each A forms a guirleway or channel in which the door F for the end of the coking chamber B beneath it is vertically movable toward and away from its normal closed position. The door when closed extends from the bottom of the coking chamber to a level somewhat above the top wall of the coking chamber.

In the construction shown, each door F comprises a cast iron frame. or rim. in which is mounted the usual fire bricli or re tractor door lining F. The metallic frame of the door is provided with flanges F which project lateralljv from the sides of the rim adjacent their outcnedges. and overlap the side edges of the doorway when the door is in its closed position. In the con-- struction shown. when the door is in its closed po ition. the flange I bear against the faces of metallic flash plates I) which are held between the faces of the battery and the usual huck stays E. There i one of these liash plates D in front of each heating wall. Advantagcrmsly. a shown. though this is not essential to the present invcntimnench flash plate is formed with an external rib D bet ween the adjacent edge of the doorway and the adjacent buck stays E. The outer side edge of each door flange F and the adjacent rib I). form the sides of a trough shaped space in which lilting! clay I1 is placed to form a tightly sealed joint at each side of the door when the door is clo ed. The joint at the bottom of the door may be sealed with luting clay L in the usual manner. At the upper end of the door. which, in its closed position, is' some distance from the top of the corresponding coking chamber. the metallic rim of the door is extended in-. wardly beyond the inner edges of the sides of the rim to cover the refractory door lining F, and preferably. as shown, is extended slightly beyond the inner face-of the latter. The marginal edge of this portion of the door conforms in shape to the cross section .of the groove A, and is separated actually scaled.

from the ide and bottom walls of thellatter only hy com airatively thin joints, which may readily be luted by clay L, As shown, the metallic top portion of the door is formed with an inclined marginal seat F on ehich the lilting clay L isi iplaced when tho door is scaled in its closed pOSll'lOH. The cndof the lilting surface on the top portion of the rim of the frame F, formed by The seat F. merge into the lltliflg' surfaces formed hy the lateral faces houses I. V

.it its upper end each door is shown as proi'idcd with an eye F'" for engagement by a suitable hoisting device. (not shown) for raking and lowering the door,

With the door construction forming the present invention, the doorsmay he opened hi simply pulling them vertically upward from their closed positions, and it one'of the advantages of my present invention that; the mechanism for raising the doors from thrir closed position, and lowering them hack into that. position may be comparatively simple. For example, the mechanism for this purpose may consist of a simple hoisting mechanism mounted o a carriage running along the track and guide rails K, ii and K. Vl'ith my present invention the advantage of a simple and easy door openin; and closing o 'ieration is combined with the chariurteristic advantages of the ordinary plug door heretofore commonly used in coke ovens of the general type illustrated. For cXzUnlJlO. an with the ordinary plug door, the refractory lining of the door in the closed position of the latter, extends into the coke oven to a depth approximately that of. or actually, as illustrated. a little greater than the thickness of the oater walls of the outer vertical lines in the heating walls at the opposite side of the coking chamber It, in conscqtience. the proper amount of heat may he supplied to the extreme end porti ns of the coal charges in the chambers ll. herchy ai'oiding black coke ends. At he sanntime, the metallic joint forming ltlt' flanges i of the door are removed an appreciable distance from the hot end f-thc coking harge and from the heating tlues This tends to prolong the life of the owtallic framework of the door, and lltls the result also of protecting the clay lilting, by which the joints at the sides of the door are from ex essive temperatures, and thereby reduces thetroubles and annoyance from the halting and crarlting of th clay lilting with resultant gas leakage during the wilting operation. it will be under tood of rhursr. that the clay lilting Hlill is iil'nh'cli and rlcstroyi-d every time an own door is opened and t'hat the door newly lutrd when closed again. 'lhr excssive halting ofthe clay lut|ngma \-'sometimes g1 re trouble also by causing thelutmg F of the l me, but it. will corresponding use material to adhere so firmly to the oven door as to make the joint difficult to break in opening the door, and to materially increase the trouble experienced in clcaninooff the door and oven prci'iarat'ory to the fresh lilting of the joint when thedoor is subsequently closed again. By proportioning the parts so that the upper end of the door, when the latter is in its closed position. is appreciably above the top wall of the cham- )0! B, the metallic frame work portion forming the top of the door, and the clay for sealing the joint. beta "een the upper end of the door and the bottom and side walls of the groove A are also protected against direct exposure to the high coking chamber temperatures. i

The particular arrangement of flash plates disclosed, with marginal ribs or flanges 1) between the adjacent doorways and ad acent huckstays, forms no part of the present invention, but does embody features of novelty invented by me, disclosed and claimed in my co-pending' application No. 236,712, filed May 27. 1918, for patent.

In accordance with the provisions of the statutes, I have illustrated and described the best form of my invention now known to be apparent to those skilled in the art that changes may he made in the form of the apparatus disclosedwithout departin; from the spirit, of my invention, as set forth in the appended claims, and that in some cases, certain features of the inventioifmay he used with advantage-without; a of other features of the invention.

Having now described my invention, what I claim as new and desire to secure by Letters Patent, is: V
